hi all,we have an application that requires powering an eMMC down and then back up while the MCU keeps running. BackgroundWe're successfully using the eMMC connected to the SDMMC1 peripheral running on a 25MHz 8-bit bus, with ClockPowerSave ENABLED. ...
I want to use the TouchGFX framework in my projects, but I have no idea where to start. I'd like to know where I can find the necessary information, from selecting the screen controller to programming. I hope you can help me with this. Thank you
Hi ST Community,I have inherited a product that runs on a stm32L051k8 mcu, and I am having difficulty with using the onboard flash memory. On boot, the product checks a certain location in flash to see if there are some configuration settings stored ...
Hey everyone, I am using w25q20 external flash for writing data so I have to use the file system, I am facing an issue I am not able to open the file and write data in it, Can anyone suggest any solution to it, is very helpful. I dropped the link to ...
Hello there,I am working with CAN on STM32F103. I want my MCU to send a message right when it receives a message so I put HAL_CAN_AddTxMessage function in HAL_CAN_RxFifo0MsgPendingCallback. I tried it with STM32F4 like this and it worked fine.void HA...
SOLVED: was a problem with NSS pin, the code is GPIOA but NSS is GPIOB... thought I corrected it Hello, I am trying to read register on a RFM69HW transceiver, it uses SPI.I have used this module extensively. Works perfectly on arduinos, esp, and othe...
Greetings,I want to compile the BLE Transparent Mode sample from the Cube (Version: 1.13.1Build: 17479_20230728_0839 (UTC)) for the STM32MMB module that has a different UART port from the default which is PB6/7. Our design uses PA9/10 because we nee...
Hi STM forums,I use a stm32f205rct6tr for this projectin my project i need to send 1024 clock signals to the slave, the message inside is not inportant.but after sending around 125 bytes it stops debugging entirely, i checked it out with the oscillos...
In the ATM32H747XI datasheet Table 9 on page 89...As I read this table... Examples are...Pin Name PA1 Alternate Function AF1 = TIM2_CH2Pin Name PA2 Alternate Function AF2 = TIM5_CH3Question 1:For PA0 AF1, there are two functions listed... TIM2_CH1/TI...
Hi community. I would like to know if reading the internal temp of the mcu (using the right channel of the adc) can give you an accurate idea of the temperature of the pcb where the mcu is mounted.Is it accurate this temp?Is it sensistive to other ef...
