External Power supply for STEVAL-STWINKT1B
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 ...
Facing trouble with SMBUS RX interrupt on STM32L4R9ZI.
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...
Stack Memory start address
HI All,How to test Stack Over flow in Keil (STM32L0)Is there any document ? or any process to test Stack over flow
Resolved! How do I generate an event or interrupt from an ISR along with a interrupt identifier
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...
With the stm32h7xx OSPI HAL is there a method for extending the register address space beyond 32 bits?
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,...
How to keep program in flash memory
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...
A problem encountered at the simultaneous run of Output compare waveform and PWM
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 configured to wake up from stop mode 2, using RXNE interrupt, not able to receive asynchronous responses sent from the modem.
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...
