Hello, can the pin configuration shown below possible?We need one bidirectional UART and a CAN along with a UART TX for debugging. Questions are:It says "Pin pair PA11/12 can be remapped in place of pin pair PA9/10 using the SYSCFG_CFGR1 register" So...

Hello, I'm looking to use Timer and DMA to drive a WS2812B LED with a STM32H7. TIM8 Ch2 is connected to the LED. I would like to explain what I understand so that its clear and I can get it working.A half word transfer from a memory location to the C...

Hello,We've developed a custom board with STM32H750VB at the core. The relevant page of the schematic is attached. It is not communicating properly with the ST-Link on a STM32L053R8 Nucleo board. STMCube Programmer is the software used on Windows. Th...

Greetings everyone,I'm thinking of a setup where a STM32H7 series chip is witha 1.2V regulator powers the core directly bypassing the LDO (REG1)another regulator whose output can be switched between 3.3V or 1.8V (default 3.3V on power up) powering th...

Greetings, I'm configuring the S2-LP to act as a receiver and then strobing the reception. Sometimes the reception works and the S2-LP goes to the RX state as seen from the first 2 bytes of status on MISO . Sometime, randomly, it goes into an unknown...

OK, that I can do. Also is it possible to not assign the MISO, SCK and CS for SPI and only assign MOSI since there is a shortage of pins?

Thanks JW for the quick answer. Can you please point me to resources to get UART out of SPI MOSI?

Thanks a lot everyone for the replies. It is working now (yay!), and we don't know why it wasn't working earlier. It is very strange because in the log that I posted you can see19:04:07:318 : Device ID : 0x450 19:04:07:319 : Revision ID : Rev VWhic...

Also, the BOOT0 pin is grounded in the above circuit in the assembly. Thanks.

Hi Clive, Would using auto bi-directional chips like http://www.ti.com/lit/ds/symlink/lsf0102.pdf work? Also CMD must be bidirectional right? Thanks.
