Hi all,we are encountering difficulties in activating the compensation cell option. Even if the SYSCFG_CMPCR bit 0 has been configured as 1 we never get the READY in bit 8 (always 0).Various tests have been carried out, but to no avail, so let's star...
Hello,I'm working with two F4 STM32 boards using the SPI communication.The two boards are connect to each other using the SPI1 connectivity. The first board is configured as a Master and only send data. And the second is configured as a Slave and onl...
Hi, I've got an application which is running on an STM32F746ZGT. During in the field firmware upgrades, it has to erase part of the device's internal flash memory and then write to the flash. The problem I'm trying to overcome is to enable the device...
I know TZEN is used to enable TrustZone. At first, this made sense, but now I think about the MCU implementing the Security/TrustZone, and it sounds strange that TrustZone can be disabled. So my question is, what does it really do ? Does it really s...
Hi Team,We are using a STM32F407ZG MCU and we have a UI interface (LCD, Keypad, touch) on SPI1 polling method.We are using SPI2 and SPI3 for DAC interfacing. We have used DMA with time triggered for the SPI2 and managing the SPI3 with Timer.During te...
Hi Everyone,I use STM32L083 MCU. My code has two sections which are bootloader code and main code. Bootloader Code Start Address : 0x0800000Main Code Start Address : 0x08006400I implemented low power mode in my main code and used "HAL_PWR_...
Hello,Am using STM32H745XI device same as the disco board and external flash on QSPI (MT25QL512A) single chip flash. IAR IDE is used for development. Though there are reference driver codes available for MT25QL512A but different controller is used. I...
Hi, I am using a stm32h743zi to stablish a connection with a ESP32 via SPI. I was using SPI4 at the beginning with one board that i made using these pins:66 PE13MISO67 PE14MOSI65 PE12SCK68 PE15INT64 PE11boot cs NSSUsing the pins above my program was ...
Hi,i just tried to see the reaction on some events on a system with H7A3 cpu and was surprised:EXTI response time was 50 us ! This is a lot for a ARM cpu running at 200MHz - too much, i would say.ED: wrong timings measured, my error : pins have cer....
Hi Sir , I need your help with some questions about SPWMI:1. STM32Cube_FW_H7_V1.7.0 without Demo project, Could you provide a Demo project of SWPMI STM32H7？2. As RM said，SWPMI can serve only as Master interface, Whether SWPMI can communicate with ...
