Hi, I would like to use STM32WB55 or STM32WB30 on CR2032.I reduce CM4 to 250Khz to save voltage level, but CM0 must be set to 32Mhz to use BLE.I observed that BLE connection peak consumption is significant.May be can I reduce Tx power to reduce BLE c...
I would like to plug RS485 on VCP STLINKV3. I try to plug RTS (VPC2) on DE, but I finally saw on that RTS/CTS cannot be controled by software... Can we plug DE by an other way ?I would you like to try GPIO control, do you have simple CLI or GUI ?Rega...
Hi,I have some problems with UART4 on STM32H750. Uart4 is asynchronous RS485 mode mapped on PC11,PC10 and PA15 (DE).I tried to SWAP RX/TX without succeed. Finally, I swapped it by wire.DMA not working properly. DMA Counter works. Memory address neve...
