Hello All.Reading a register value from an I2C device assumes: Writing the device address-> Writing the register address without STOP-> Reading the value . I am trying to figure out if I can do it using only available HAL functions but I don't see h...
STM32F4 is working in USB Device MSC mode successfully.I need to detect the USB connection state. I put the HAL_PCD_ConnectCallback function in main.c but on compiling I received warning.Debug/../USB_DEVICE/Target/usbd_conf.c:307: multiple definition...
Hello ST people, I spotted an error in AN2834 rev 9, figure 8. Please refer to the image attached.A negative offset error should be depicted in figure 8, but it is a positive offset error, just like in figure 7. To be a negative offset error, the act...
Hello everyone, i would like to know the HAL function that allows to reset the value of a simple counter. I don't find the HAL function to reset my counter to 0 before a next counting. So all i want to do is to count, read my counter value and reput ...
I am a new embedded software engineer using STM32L432KC for my company's projects.I have been tasked to install a bootloader into this MCU. I am not sure how to proceed. I do understand that the BOOT0 pin which is grounded has to be set HIGH and BOOT...
Hi, 1.I want to save multiple files but only 50 or 55 files savings.and how to save files next to next file.I want to fo fill data files up to to 32 GB. 2. how to reuse same memory for multi file creationint main(void){ /* USER CODE BEGIN 1 */ /* U...
Hi.I want to save and load data to flash memory. (STM32F373RC)And initialization code was generated through cubemx.All functions including SPI, I2C, and ADC were successfully tested.However, saving and loading data into flash memory failed.All functi...
Hi everyone,First I am sorry for the uneducated rest of this text and badly written code.I am currently playing around with a stm32f4 chip. I am using Platform IO CMSIS and a cheap stlink v2 to program the chip. I was trying to get PWM working when t...
Hello, Am using STM32L412RBT6 controller to generate PWM for our battery charger product. We need to generate two PWM's and am using TIM1_CH1 and TIM1_CH1N pins to generate 2 PWM's. These are all configured through Timer1. Here i have a requirement,...
Hello, I am building a time critical application with SPI output communication using DMA circular bufferI need to output data at a very precise frequency that is a multiple of 0.125 ns. Normally it should be 4us but It would need to be sometime 3.9us...
