Antichambre 200 Posted December 21, 2020 Author Report Share Posted December 21, 2020 (edited) With J15.DC pin ;) Edited December 21, 2020 by Antichambre Quote Link to post Share on other sites
Phatline 89 Posted December 22, 2020 Report Share Posted December 22, 2020 ok could you also check if SC RC of J8-9 are ok on this shematic? (is the symbol the actual one?) ... in the past there where Crossed RC SC lines.... Quote Link to post Share on other sites
Antichambre 200 Posted December 22, 2020 Author Report Share Posted December 22, 2020 (edited) If I remember well, the pins I crossed on the first proto were J16.SI and J16.SO. J8/9 seems good on your schematic but pin 40 and 39 are still reversed!!! 39 ->J16.SO 40 ->J16.SI More than that I added the USB Host, it doesn't appear on your pinout. Note: USB HOST supports: USB MIDI Device. USB HID Keyboard and Mouse. attached the eagle lib.dipCoreF4_v2b.lib Edited December 23, 2020 by Antichambre Quote Link to post Share on other sites
Phatline 89 Posted December 22, 2020 Report Share Posted December 22, 2020 (edited) dipCoreF4-v2b-KICAD.zip i converted it into Kicad.... 3 different symbol sizes of the 52pin. Edited December 23, 2020 by Phatline 1 Quote Link to post Share on other sites
Phatline 89 Posted December 23, 2020 Report Share Posted December 23, 2020 if i want to use the onboard USB not to be onboard? In sense of routing to a Connector on frontpanel... in order to load new code into it.... i mean the one for flashing new Mios Applications... is this possible, which are pins to go? (a few of them are host-mode i guess) Quote Link to post Share on other sites
Antichambre 200 Posted December 23, 2020 Author Report Share Posted December 23, 2020 (edited) Sorry not the good lib! This one is fine: USB1(old) FS, Device/Host, this is the one you have to use, ID is floating for Device Mode, ID to GND for HOST 41 - USB1.ID = ID pin for USB1 46 - VBUS = VBUS for USB1 43 - USB1.DP = USB1 D+ 48 - USB1.DM = USB1 D- USB2(new) HS in FS Mode, Host only. 44 - USB2.DM = USB2 D- 45 - USB2.DP = USB2 D+ 49 - USB2.OC = Input for external overcurrent sensor. 50 - USB2.EN = Ouput for external power switcher dipCoreF4_v2c.lbr Edited December 23, 2020 by Antichambre Quote Link to post Share on other sites
Phatline 89 Posted December 27, 2020 Report Share Posted December 27, 2020 (edited) ok here is the kicad library for the V2C dipCoreF4-V2c-kicad.zip (as 3D Modell i took a IC-Socket + a Dip40 IC on it...) Edited December 27, 2020 by Phatline Quote Link to post Share on other sites
Antichambre 200 Posted December 28, 2020 Author Report Share Posted December 28, 2020 (edited) Thanks! Wiki updated!http://www.midibox.org/dokuwiki/doku.php?id=dipcoref4#download Edited December 28, 2020 by Antichambre Quote Link to post Share on other sites
Phatline 89 Posted January 2 Report Share Posted January 2 i made a nother design with your Dipcore as brain (clock2audio2clock) I need one more LED in this shematic: every pin which is no connected (yellow cross) - i dont need - so these are possible for LED. any possible? thx 4 help - mike Quote Link to post Share on other sites
Antichambre 200 Posted January 2 Author Report Share Posted January 2 You can use any pin, they are all GPIO(General Purpose In/Out). You just need declare the port of the pin as not used (MIOS32_DONT_USE_XXX) and use the GPIO_InitTypeDef. Quote Link to post Share on other sites
Phatline 89 Posted January 2 Report Share Posted January 2 ok then i take J16 RC2 (PA4) and J16 RC1 (PC4) which are used for SD-Card - which i dont need here. so i gues MIOS32_DONT_USE_SDCARD ? @ Type DEF - is this done like on J10 for example: MIOS32_BOARD_J10_PinInit(0, MIOS32_BOARD_PIN_MODE_OUTPUT_PP); MIOS32_BOARD_J10_PinSet (0, 1); for me Clear how to make it with J5 and J10 >>> MIOS32_BOARD_J16_PinInit(0, MIOS32_BOARD_PIN_MODE_OUTPUT_PP); ??? thx Quote Link to post Share on other sites
Antichambre 200 Posted January 2 Author Report Share Posted January 2 for J16 which is a SPI port MIOS32_DONT_USE_SDCARD MIOS32_DONT_USE_SPI0 Init // common GPIO_InitTypeDef GPIO_InitStructure; GPIO_StructInit(&GPIO_InitStructure); GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz; GPIO_InitStructure.GPIO_Mode = GPIO_Mode_OUT; GPIO_InitStructure.GPIO_OType = GPIO_OType_PP; // J16.RC2 as GPIO (PA4) GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4; GPIO_Init(GPIOA, &GPIO_InitStructure); // J16.RC1 as GPIO (PC4) GPIO_InitStructure.GPIO_Pin = GPIO_Pin_4; GPIO_Init(GPIOC, &GPIO_InitStructure); then to set or clear the pins you can use the macro: // MIOS32_SYS_STM_PINSET(port, pin_mask, value) // e.g. MIOS32_SYS_STM_PINSET(GPIOA, GPIO_Pin_4, 0) MIOS32_SYS_STM_PINSET(GPIOC, GPIO_Pin_4, 1) 1 Quote Link to post Share on other sites
Antichambre 200 Posted January 3 Author Report Share Posted January 3 @Phatline close the VBAT jumper, on the bottom side if you use the pin 32 as 3v3 output. Quote Link to post Share on other sites

Yes need it for a MCP6002 Rail.... is the jumper on the BOTTOM of the Dipcore? Quote Link to post Share on other sites

Phatline 89 Posted January 24 Report Share Posted January 24 (edited) hmmm... serios problems here when i connecting the dipcore via Dipcores-onboards USB-Socket to my Laptop (lenovo thinkpad t440p, linux mint): i get after a few seconds after booting up a: !! HARD FAULT !! at PC=0x0801afd4 or it doesnt boot at all it doesnt matter if the Laptop is on battery only, or with PSU-connected (so it isnt a noisy psu) I doesnt measured a Voltage Dropdown on the USB-RAIL (measered on the PTC) while Hardfaul accours... i doesnt Activated "Midi via USB" since config is: #define MIOS32_USE_MIDI #define MIOS32_USE_UART #define MIOS32_USE_UART_MIDI #define MIOS32_UART_NUM 1 #define MIOS32_UART0_ASSIGNMENT 1 //1=Midi, 0= Disabled, 2= COM #define MIOS32_UART1_ASSIGNMENT 0 #define MIOS32_UART2_ASSIGNMENT 0 #define MIOS32_UART3_ASSIGNMENT 0 (right?) it doesnt fault (no time) when i connect the same USB to a Mobilphonecharger (2A) and it doesnt fault ... when running (almost) the same app on LPC17 > CV1 ok that tell us NOT much, because the LPC17 is no STM32 chipset... ... also most of the time the Dipcore isnt regognized via MIOS-Studio - i have to go into Bootload Mode(via Switch) to upload new code.... (i dont scan any J5 or other GPIOs which could force floating data mess) --- i updatet today the repo from your github... so its actual ( i cant say if it worked before... its long ago since i codet on a dipcore) i tried different USB ports from my laptop, also the one Port which is a "always on to charge whatever usb) make the same hard fault The app doenst boot up on a windows 10 Desktop PC at all (no time!) (no screen content on the SSD1306) on a other windows 10 Desktop it boots, but it Hardfaults the same way like on my Linux laptop. i bridget the VBAT! (use SD-Card and SSD1306!!!), because i have to supplay a "motherboard" > CV-1-Shematic.pdf i already had deactivated all SD-Card Routines, and Scan Routines, but the machine hangs on almost "background" tasks... so i turned it on again. here is the APP i programm... CV-ONE-V0.zip ==============================================================0 i use the bootloader from here: http://wiki.midibox.org/doku.php?id=dipcoref4 > (i dont change anything in bootloader via Terminal --- i changed the display settings within the app --- so its almost stock) http://wiki.midibox.org/lib/exe/fetch.php?media=antichambre:dipcoref4_bootlader.zip i updatedt today the mios repo from: https://github.com/antichambre/MIOS32 gcc-arm-none-eabi is still from 2013 ( i dont updatet anything there) and of course the environment variables are set correct: MIOS32_PATH=~/midibox/mios32 MIOS32_BIN_PATH=$MIOS32_PATH/bin MIOS32_BOARD=MBHP_DIPCOREF4 MIOS32_FAMILY=STM32F4xx MIOS32_GCC_PREFIX=arm-none-eabi MIOS32_PROCESSOR=STM32F405RG MIOS32_LCD=universal the app is functional as i said but not on computers... on smartphone chargers i dont get a Error!

Phatline 89 Posted January 24 Report Share Posted January 24 (edited) I updatete the repo, and deletedet the uneccersery lines in mios-config. its no long test, but on the moment its running without HARD-FAULT, and it is recognized in Mios-studio without Bootload-Mode! thx! BUT now Display1 stays dark, it is connected to Pin 33, PB12-J15.CS1 (it was working bevore) Display 2 is working, it is connected to PIN 27, PC0-J15.CS2 Edited January 24 by Phatline Quote Link to post Share on other sites

I swapped (mios config side) Y to2, and X to 1 - and now it works.... I dont understand this, it was a X2 Y1 bevore. (crazy) ok later the day one display fault again.... (same code) i measured the "Reset" Resistor (1K) and i had 760OHM... the Reset Voltage was about 2.5V.... on the working Display i had 3.3 Volt - and a Resistance from 980 Ohm.... (1Ks are installed)... so i cleaned the soldering Points of the display, after removing the FLUX i got a Working LCD and a Voltage from 3.3V .... low impadance Flux - GOOD NIGHT!
