novski Posted March 10, 2014 Report Posted March 10, 2014 Hi. Wondering if the Schematic of STM32F4 is still Prototype or just the Boardlayout has to be checked? Can someone confirm that the Schematic is out of beta-stadium? Thanks Novski Quote
sneakthief Posted March 10, 2014 Report Posted March 10, 2014 The beta checked out fine here. There was only one correction that I was advised of in addition to the footprint of the SD-Card that was being changed. The last update has been completed by Smash and it's on its way to be fabricated: Quote
novski Posted March 11, 2014 Report Posted March 11, 2014 Hi, i have problems understanding how to connect my 24 OLEDs. I can't find J28 on the schematic and also no infos on ucapps... I know the doku is not ready yet but... :rolleyes: Thanks Novski Quote
novski Posted March 13, 2014 Report Posted March 13, 2014 Does nobody, have a idea how to connect J28? Thanks for help! Best regards Novski Quote
sneakthief Posted March 13, 2014 Report Posted March 13, 2014 novski: did you see this? http://www.ucapps.de/mbhp/mbhp_lcd_ssd1306_alt_port__stm32f4.pdf ...J5/J10B? static u8 lcd_alt_pinning = 0; // alternative LCD pinning (e.g. for MIDIbox CV which accesses a CLCD at J15, and SSD1306 displays at J5/J28 (STM32F4: J5/J10B)) http://svnmios.midibox.org/filedetails.php?repname=svn.mios32&path=%2Ftrunk%2Fmodules%2Fapp_lcd%2Funiversal%2Fapp_lcd.c&rev=1937 Quote
novski Posted March 13, 2014 Report Posted March 13, 2014 Thanks for that! Its close but does not fit for my 24 oleds.... Seams to be not implemented jet... Il stick to LPC17... Best regards Novski Quote
TK. Posted March 16, 2014 Report Posted March 16, 2014 It is implemented: J10B is used instead of J28 Pinning: J10B.D8: serial data (was J28.SDA on a MBHP_CORE_LPC17 module) J10B.D9: serial clock (was J28.SC on a MBHP_CORE_LPC17 module) J10B.D10: SR strobe (was J28.WS on a MBHP_CORE_LPC17 module) Note that these assignments are not pin-compatible to a DOUT module anymore!

novski Posted March 22, 2014 Report Posted March 22, 2014 (edited) There are diferences on the schematic of STM32F4Discovery! J10A/B show different labels then the arrows out of the Discovery uC pins. J10A D0 => PE8 D0 - correct J10A D1 => PE9 D2 J10A D2 => PE10 D1 J10A D3 => PE11 D4 J10A D4 => PE12 D3 seams like something swapped all odd to all even numbers on ether J10 or uC side... Hope you didn't make a mistake with the new core pcb! I'm looking forward to get it... :smile: best regards novski Edited March 22, 2014 by novski Quote
TK. Posted March 23, 2014 Report Posted March 23, 2014 Yes, you are right, the connections are wrongly named at the Discovery side, they are correct at the J10A side. I can fix the schematic in ca. 2 weeks... The PCB has the correct connections. Best Regards, Thorsten. Quote
eptheca Posted April 4, 2014 Report Posted April 4, 2014 (edited) I am trying to get MIDI IN from a 5 pin DIN Can I use a "standard" MIDI IN circuit, like the Core8 circuit, with 5V and connect it to PA3? Or do I have to use the new MIDI I/O board? Never mind I just used the MIDI IN circuit from LPC 17, and it worked :) Edited April 4, 2014 by eptheca Quote
IImyMent Posted April 4, 2014 Report Posted April 4, 2014 Hi, I m trying for the first time to use mios on a stm32f4..01that I missed purchased thinking that would be compatible with the bootloader and the app. Unfortunately it doesn't work as I expected and it seem the spec are different enough to create troubles. At the same time I purchased a real discovery one with the right ref stm32f407: so far so good it works for now the way it should. Could any one point me in the right Direction on how to update the sources to make the work with the mispurchased one? Just to let you know I m building a tr 808clone coming from microlarge website... And I intend to control it the mios. Thanks again Quote
TK. Posted April 6, 2014 Report Posted April 6, 2014 Hi, many files have to be changed to support another STM32F4 derivative, especially when it's smaller (memory & package wise) than a STM32F407! Even for me this would take a couple of hours (therefore I can't give you simple instructions for the required changes). Most difficult topic is to decide the IO pin configuration for the reduced 64pin package. Many peripherals won't be available. However, since you already own a STM32F407, it's probably better to skip this idea anyhow. Best Regards, Thorsten. Quote
IImyMent Posted April 11, 2014 Report Posted April 11, 2014 (edited) Hi, thanks for your quick answer. I'll stick on the original right reference with stm..407. It's sound definitely like the wise choice for now on, at least for me. Having said that the second discovery I have is a STM32F401VC which seems to have the same number of pin as the 407 (don't know what it means but it is 100pin LQFP for both). I start again to hope that could it be done. At least if it was possible, troubles would not come from this part. I wonder which files are specifically written for the 407 or the 401 for the bootloader to work and if it is only a question of few lines to be change or as you were suggesting something to complex to be updated? Edited April 11, 2014 by IImyMent Quote
TK. Posted April 12, 2014 Report Posted April 12, 2014 The most simple strategy would be the following: - download the repository into a separate directory and change your MIOS32_PATH accordingly - change the PLL frequency configuration in mios32/STM32F4xx/mios32_sys.c, because STM32F401 can only be clocked at 84 MHz I assume that the corresponding SFR configuration can be found somewhere in the internet - compile a new bootloader under bootloader/src with "make STM32F4DISCOVERY"; this will refresh mios32/STM32F4xx/mios32_bsl_STM32F4DISCOVERY.inc (this step requires a perl installation) - recompile bootloader/updater and program it into the flash If this already helps, let me know about the changes and I will consider MIOS32_PROCESSOR=STM32F401VC in the main branch, so that you can use a common repository again.

rvlt Posted June 3, 2014 Report Posted June 3, 2014 Hey, I got my STM32F4 core pcb from smash and almost finished it except the sd card socket. In are pictures of two different sockets. I think I found the 3M one at mouser (mouser-no. 517-SD-RSMT-2-MQ). - does anyone know what brand the other one is? - does anyone know where to get either one of those in germany (or europe) apart from mouser? their shipping cost is 20 euros… - can I still connect a sd card socket via J16 if I don’t use the „internal“ one? Cheers Lars Quote
sneakthief Posted June 3, 2014 Report Posted June 3, 2014 I'm doing a Mouser order this week - do you want me to buy this one for you? http://de.mouser.com/ProductDetail/3M-Electronic-Solutions-Division/SD-RSMT-2-MQ/?qs=sGAEpiMZZMuJakaoiLiBplDeQSW3avr%252bjCB3FYuNrDg%3d It looks like the correct one. You can pick it up from me in Friedrichshain. Quote
novski Posted June 3, 2014 Report Posted June 3, 2014 Same from me in switzerland, just in case.... br Quote
TK. Posted June 3, 2014 Report Posted June 3, 2014 - can I still connect a sd card socket via J16 if I don’t use the „internal“ one? yes Best Regards, Thorsten. Quote
rvlt Posted June 3, 2014 Report Posted June 3, 2014 You guys are awesome!!!!!! Thank you! sneakthief, that'll be perfect, I'm in Friedrichshain, too! I'll send you a PM now... Quote
rvlt Posted June 3, 2014 Report Posted June 3, 2014 And what's even more awesome: me and sneakthief just discovered we live in the same street and are almost neighbors since eight years... :D :D Quote
sneakthief Posted June 3, 2014 Report Posted June 3, 2014 Yes, we can start the local chapter of the MIDIbox Armee Front :D Quote
rvlt Posted June 7, 2014 Report Posted June 7, 2014 Just wanna confirm that these 3M sockets work really well... Thanks again sneak-thief Quote
