However, I am getting 0x3A(NACK) in stop condition of my logic analyser. Can anyone help me how i can convert this NACK to ACK. I am attaching my code snippet and my logic analyser signal as well . Thanks for help and support.uint8_t I2C_ADDRESS = ...
I've defined the lower 8 bits of a STM32F4 GPIO port as a negative-true open-drain output. My current code uses two 16-bit writes, first to set all 8 bits, then another to selectively clear them. It would seem that I could do this with a single 32 b...
Hi All, I am using the STM32H723 device and have 8 GP outputs going out to a GreenPAK device to set the exact bit delay and muxing the outputs per the customer configuration. Due to the nature of the application, I cannot afford to integrate the logi...
Hi everyone, this is my first time posting a question.I use the MX25UM51245G OctoSPI Flash memory of the STM32H7B3LI Discovery Board. Use stm32cubeIDE. I have referred to STM32L4 Octo-SPI Application note and STM32H7 Octo-SPI Application note.But I s...
Hi Guys,I got an error while debugging codes to my STM32F439 MCU with ST LINK V2. I could not solve it but if I debug it for STM32F429 Nucleo Board I can debug. I can not understand. I wait for helps. Thanks.
For the upcoming project planning to use the STM32H family of uC and try to run code from flash bank1 and use the bank2 for staging the new firmware.Once staged firmware CRC check would like to swap the code from bank2 to bank1 and reboot the device ...
Hello everyone :D I am currently using the STM32H743VIT6 (LQFP-100) on a custom PCB.My goal is to generate fast positive pulses (ideal case would be a 10ns pulse) on TIM4 CH2 (PB8). APB2 is clocked at 200MHz so I can get 5ns ticks from my timer.Gener...
Hi!!! I am using STM32H743BIT6 MCU and I want to measure the speed of reading a binary file (image) in SDCARD.SDMMC1 is set and SD 4 wire bus is set.On which pin should I take the measurement on the MCU? Also, the unit of speed is (Mbyte/s). Is it...
