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...
Hi, I am currently working on a Embedded software application which require multiple SPI, UART peripherals/ pinouts(Min 2). I have used SDP-K1 (MCU- STM32F469) Eval board for my previous project which is suitable for my current project as well except...
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
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...
Hello, I am using the STM32f107vct6 which has 256kbyte flash memory size. However, after connecting to MCU via st-link V2 and ST-link utility it shows me just a few pages of my flash memory size and the wrong flash memory size.what is my mistake?
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...
Hi all,I'm working with STM32F4 disc board, I'm using PB8 and PB9 as interrupt input, those pin shared same irq handler EXTI9_5_IRQHandler I would like to know if it is possible to only deactivate the interrupt on PB8 before STOP mode but leave the...
I have an MT25QL01GBBB8ESF-0SIT controlled by an STM32F765VGT6 microcontroller. This was coded using C and the STM32 HAL in the STM32CubeIDE. It was verified working using different SPI commands such as read JEDEC ID, page program, etc. However, afte...
I recently started working on a custom board project based on an STM32G070CBT and using the SWD interface through an ST-Link Debugger. The previous developer is no longer working, and all he left behind was the Keil uVision project. So, everything sh...
Hi, We are using STM32G070RB for our application. Need a reference design for the schematic & also as mentioned in below screenshot there is requirement of L1 inductor on AVDD pin, Please let me know the Required value of inductance/impedance or plea...
