How to calculate the Nand flash timing when I config the FMC for a nand flash?
Hi there,I want to use a nand flash(H27U1G8F2BTR) by stm32f429BIT6.I config it by stm32cubeMx, but many timing parameters need to be set.I find some documents about "How to calculate the timing" in AN4570(page 34):It's said the equations are followin...
How to enable write protection using I2C bootloder protocol
Hi all,I wanted to enable the write protection option byte using I2C bootloader ( Bootloader given by stm32). This can be done using the stm32 debugger also. but in my case requirement is using I2C bootloader only. MCU : STM32G0B1CET6communication pr...
STM32L431 I2C master transmitter: TXIS is set when slave NACKs
My setup is STM32L431 with Sensirion SHT31 connected to I2C1. This setup works normally under usual conditions, but when the sensor had intermittent connections, the software started to behave unexpectedly. Following is simple experiment where I walk...
Resolved! how does HAL_ADC_Start_DMA() behave if the DMA is set to half_word
HAL_ADC_Start_DMA() takes a pointer to a uint32_t buffer, but the cubeMX can configure the DMA for word, half_word or byte.So therefore you can only configure the DMA for word transfers?I was setting the cubeMX to half_word or uint16_t and using 12bi...
Resolved! I2C Slave address
Hello everyone!I am making a project with STM32F072 MCU and I have 3 devices that need to be controlled via I2C: a DAC, an ADC and a current monitor that has an ADC integrated. I've made the connections and part choices so that I have 3 different 7-b...
program MCU via system rom bootloader and CANBUS STM32F2
hello :)I am trying to program my MCU via system ROM bootloader. I have read an3154-can-protocol-used-in-the-stm32-bootloader-stmicroelectronics reference manual &an2606-stm32-microcontroller-system-memory-boot-mode-stmicroelectronics. I wrote a C++ ...
Resolved! The correct value cannot be read without resetting after flash writing with the B-U585I-IOT02A
I use B-U585I-IOT02A to read after writing Flash Memory, 0xFF is read, but once I reset it, I can read the written value.Similarly, when I use it to read after erasing the Flash Memory, the value before erasing is read, but once I reset it, I can rea...
