I was trying to read the 24AA64FT EEPROM using the I2C DMA methods. But the I2C read will break after reading 2 bytes for no reason, and both SDA and SCL stay low. As you can see in the picture, the reading starts with writing 0x50 (0xA0 >> 1) to the...
I have the following bug in my project and cannot figure out why.In one function I was using an uninitialized pointer variable to receive data from another function. For some reason it works which I think shouldn't. The code is like this:funcA{ m...
I hate being stupid, but I'm trying to get a nucelo-stm32LR76RG eval board working. I have the cubeide and cubemx software installed. I also have the associated example programs loaded. The board comes shipped with a program that makes the led blink ...
This is a follow up to the Topic OctoSPI configuration for hyperflash, as I do not think it has a definitive answer. I have the cypress S26 Hyperflash Memory connected to the OSPI Interface and configured it for Hyperbus transaction. Also I want to u...
This is my simulation output waveform.They are CH1, CH1N, CH2, CH2N, CH3, CH3NIt can be seen that CH1, CH2, and CH3 are all normal, but the complementary waveforms will be affected by other channels.How can I configure it?I want to use multi-channel ...
With my STM32F7508-DK board, I am interfacing to a BLE board over UART without hardware flow control. Due to pin conflicts, RTS/CTS is not available on that board. My primary issue is when BLE board sends 10K text buffers, STM32F7508-DK UART stops Tx...
Hi All,I want to use DMA to receive unknown length data. So I config USART_IT_IDLE and DMA_IT_TC and set DMA_BufferSize = 30 bytes. When the length of received data is less than 30 bytes, It works correctly and enters the USART1_IRQHandler(void) func...
I clicked on the function of on the fly startup.It seem can't work in headwind. It can work in downwind.Does anyone have suggestions ?Thanks.
I cannot to set NSS pin in push-pull mode. What is may be wrong?I use SPI1 on stm32F7 as a master only mode with SSOE config bit. My system use SPI clock speed 13,5 MHz. GPIOA#4 is used as NSS pin alternative function 5, push-pull output.This configu...
Hi Experts,I have a project like below. I am trying to send the data but the LEDS are not glowing in sending pattern.I am new to STM32F207 Nucleo board. Could anyone please let me know if I am missing anything.STM32f207 ======> CD4094(Q0) ==========>...
