Resolved! STM32L432 Internal Temp Sensor

I'm trying to get the internal temperature sensor working on a custom board with an STM32L432KC. VDDA is 2.5V and is stable. The raw readings I'm getting are about 200 counts higher than I would expect on a 12bit config. The reading doesn't change ba...

ECC on CPU Registers

Do any of the Cortex M4 or M33 based MCUs have ECC on the processor's registers?If not, is there a mechanism built into the processor to ensure that processor registers (R0, R1, R2...R15 etc) are not corrupted due to SEU?Regards,Hamid

Resolved! CORDIC COS gives negative result

I am testing CORDIC module on STM32H723ZG. The results from CORDIC_FUNCTION_COSINE calculation are consistently negative where they should be positive and vice versa. This holds for 32BIT calculations and for 16BIT as well. Cannot find why this is ta...

Resolved! High Speed Memory array copy

Hello, I have implemented a high-speed USART @921600 baud rate with STM32f10x @72Mhz. I want to send 3000 Bytes to a slave MCU.In slave MCU, I used USART DMA to read MSG[300]byte data collect the data, and copy them into a larger array(Data[3000]).My...
