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,...
I am trying to use STEVAL-STWINKT1B for predictive maintenance application as an standalone device using Battery pack provided in the kit. But i need to flash the program everytime i remove the battery. I wanted to know if there is a way to keep it w...
I am using STM32F407. I am using TIM1 for output compare waveform running at 5Mhz and TIM9 for 250Khz waveform. Output Compare is used to produce a waveform of desired data. However, both timmers run fine individually, but if both are run simultaneou...
STM32L462 is configured to wake up from stop 2 mode on RXNE interrupt. Since the response length is unknown and dynamic, have configured interrupt on every character till the end of character is received. MCU is successfully waking up on UART recepti...
i want support for how to connect both board with each other. i want supporting document for it.i want examples to learn about them.
Hi,I am trying to init SPI1 (to just receive data qwith MISO) on nucleo G474RE without using HAL libraries.Can you help me to assess why my code does not work ? I can't see the clock eventhough SPI1 is enabled void SPI1_init(){ RCC-> APB2ENR|=(1 AHB...
We are using NUCLEO-L053R8 board for testing. We are measuring the current through JP6 (IDD)
what will be the maximum size of external parallel SRAM & NOR flash, that can be interfaced with STM32F429IIT6?
Shouldn't just the RXNE flag trigger with this code? or does the outgoing transmit message also generate an RXNE flag?Thanks!
