I am trying to do control one STM32-L476RG using another STM32-L476RG via UART/USART. For now, I would like to turn on the LED of the "slave" STM32 using UART from the "master" STM32. Is that possible? If so, how? Thanks.
I'm using an STM32L051R8 in STOP mode with a 32.768KHz external crystal (LSE) that drives the RTC.I have set the RTC to generate periodic wakeup interrupts every X seconds, It's working.But I also want to wakeup using the external interrupt, whenever...
Hello, I'm trying to implement the temperature sensor TSYS01 on STM32U575I-EV.The datasheet of the sensor tells to reset the sensor first so I'm trying to do this like this:HAL_I2C_Master_Transmit(&hi2c2, 0x77 << 1, 0x1E, 1, HAL_MAX_DELAY);0x77 << 1 ...
I wanted to know if there was any external power supply available to power the STEVAL-STWINKT1B board instead of giving it power through the laptop or the provided battery pack. I wanted to implement it in an industrial setup and keep it on for the ...
Hello, I am facing a strange issue. I have a SMBUS battery and a LTC4100 battery charger chip connected to the micro controllers I2C1 configured as SMBUS. The charger has address 0x12 and the battery has 0x16. All communication is going correctly and...
HI All,How to test Stack Over flow in Keil (STM32L0)Is there any document ? or any process to test Stack over flow
I have an app with a pretty simple non blocking state machine that works pretty well. There are a bunch of UART and I2C devices along with a couple of timers that all have ISRs. When an ISR gets called, it puts its data along with an identifier and a...
I'm at attempting to create a driver for a HyperRAM IC based on the the s70kl1281 DK driver. Where the s70kl1281 limits its register address space to 32 bits, the chip I'm attempting to access (the W957A8MFYA5I) has a 36bit address space (or 40 bits,...
