So the datasheet says "Min VREF+ Positive reference voltage - 1.8 V (1)(2)(3)", and note 3: VDDA -VREF+ < 1.2 V, so with VDDA at 2.925v, VREF of 1.755V would be permitted? Its a bit confusing to me at this point!Given the ADC 12 bit resolution, the L...
I made a simple program on an ESP32 to send dummy data with something like this $DUMMYDATA,0,1I've tried using another ESP32 as a receiver and it works perfectly. My goals is implement the same thing to my STM32F103C8T6. Here's my code for the first ...
Hi All,I'm working on a STM32H7 custom board and I'm trying to access a Cypress S70KL HyperRam through the Hyperbus protocol using the OCTOSPI1. I'm able to access in read/write the HyperRam but I want to use the delay block therefore in CubeMx I ena...
What is the role of syscalls.c file in GNU ARM(STM32 for instance) based projects? I found 2 ways of successfully building the project1. Delete syscalls.c and include -specs=nosys.specs in the linker flags2. Simply include syscalls.cWhat is the funda...
Hello again everybody. I have run into the following problem: I try calibrate the ADC1 and plain calibration seems to work just fine (apparently), but as soon as I try to follow the Extended Calibration procedure, described on page 1007 of the Holy U...
Dear Sir.I need the output of the ADC to be signed .the adc is configured . /** Common adc1 configuration */ hadc->Init.ClockPrescaler = ADC_CLOCK_ASYNC_DIV1; hadc->Init.Resolution = ADC_RESOLUTION_14B; hadc->Init.DataAlign = AD...
I cannot get the CAN bus CAN1_RX0 interrupt to fire. I have two other development boards (STM32429i-EVAL1 and STM32373C-eval) that both work correctly. I am using the same code in each setup thru the ST MX and IDE. The Eval boards have built in C...
I'm trying to set up the SPI5 for a test but see a lot of references online indicating the pins modes need to also be set. I figured the driver would do that. The init seem pretty straight forward. but the transmit does not. Do I need to set my pin m...
