I am using the Bluepill board. I want to generate PWM signal on Timer2 and set up a timer interrupt at 20ms interval on Timer3. I realized that the PWM signal cannot be generated if I set up the timer interrupt on Timer3. How do I solve this problem?
I hope this thread is posted in the right category.I’ve been using Arduino boards for several years and am thinking of using a Nucleo 144 board (specifically, Nucleo-F207ZG) for a project. Once the project is completed, it will be serve as a permane...
There's the Flash Size Register in the Device electronic signature. Is there an equivalent for the onboard SRAM size? Any way to get the ACTUAL SRAM size at runtime?
This has been a reoccurring issue for me, whenever I raise the ADC frequency above 0.25MHZ the while loop gets interrupted, and when I use frequencies below that the ADC resolution drops to 8 bits for an unknown reason. Is there a way to fix this wi...
I'm using STM32L031E6Y6 for a high volume low cost product and I'm hoping to arrange it so that even if my firmware binary were to be stolen, it could only be used to produce a limited number of counterfeit products.I can cryptographically fix the fi...
We need to transmit and receive I2S data at the same time.But we can’t transmit and receive at the same time now.Then we want to know whether the SAI of STM32L433 can achieve features similar to full-duplex?If yes, is this setting correct?
Hello,We are planning on replacing the F042 (TSSOP20) with the G0 cited in the question.At the moment the F042 use a HSE crystal of 8MHz in order to get a precise enough clock for the CAN peripheral.Parsing the datasheet of the G0B1KB, there is no wa...
Got a new batch of micro's from a broker due to the chip crisis. They work and soldered down fine, memory matched, bootloader, etc. The concern about these MPU's is the silk screen and die marks are quite different.We have never seen die marks on the...
I want to create a localhost that my client can easily see a custom page on, that is displaying all the data from fish tanks. Such as, temperatures, water levels and more. What products would be ideal to use? A NUCLEO-f767Zl??? BUT, then theres the a...
Hi guys, its been a while and I hope everyone is well and safe.Using a STM32H743ZIReference Manuel I am having issues turning on the DMA1 stream associated to the UART4 Tx, in this case DMA1_Stream1. The DMA is setup as a One Shot mode (Normal Mode) ...
