Zam Posted January 6, 2020 Report Posted January 6, 2020 Great work Thorsten !! Side question, is it possible to hook ESP32 and STM32F4 cores with direct midi/UART connection (high speed without opto like I do between 3 STM core here) And use it as a RTPM wifi bridge ? Best Zam

Or prepare the ESP32 as a SPI-MIDI slave like a kissbox?
TK. Posted January 6, 2020 Author Report Posted January 6, 2020 Actually I wanted to provide SPI slave (see some postings above), so that the module can be connected to J28 instead of ENC28J60 But a UART connection is available as well - and the baudrate is configurable by default. As long as you only need a point-to-point connection, UART is a good choice. But for accessing multiple ports (e.g. BLE and Apple MIDI) SPI would be better, because it considers multiple "cables". Best Regards, Thorsten. P.S.: in context of MBHP_MF_NG: only UART option will work, because SPI is already used for other purposes.
FantomXR Posted March 7, 2020 Report Posted March 7, 2020 So meanwhile: is it worth replacing the PIC with the ESP? I'm designing a PCB for MF NG by myself. So if the PIC is outdated I'd upgrade to an ESP up front.
