I have single channel ADC measurements on ADC1 and ADC2 working with an STM32H753IIK.I need to measure VBAT, Tempsensor and VREFINT, which the source code says is ONLY on ADC3.I generated the following init code:void MX_ADC3_Init(void) { ADC_Channe...
I am trying to modify my own I2C driver (I don't use Cube) - to talk to a BQ32000 device - it's a I2C RTC chip.The protocol is shown in the picture below.The protocol to read requires a "restart" after sending the chip's address and sub-address to es...
Posted on September 02, 2014 at 02:20I'm trying to connect from an STM32's FSMC to block-RAM inside an FPGA. Since this type of memory is synchronous, I need to expose the FSMC clock to the FPGA.At the moment I have an STM32F4-Discovery connected to...
Hello,I have an application that reads a couple of ADC channels. each time through the main loop. There's no It's a blocking ADC read so nothing else is going on when I'm reading the 2 channels. For testing purposes I have a 3V battery attached to...
When I cut the STLINK module the nucléo board don't workIt whork's before cutExternal power E5V Thank you
I can't choose this with the product selector (at least I don't know how :-))Could you please help?Thanks a lot.Joerg
The MCU qspi peripheral is connected to serial NOR flash. Along with these connection the same qspi individual data pins are connected to 3 individual Altera FPGA for booting purpose.qspi clock is common for all 3 FPGA.The following operation which a...
I'm trying to read the internal temp sensor of a STM32F030F4Px but datasheet isn't clear about how to calculate it.Vsense = ( 1686 / 4095 ) * 3.3 = 1.35VTemp = ((1.43 - 1.35) / 4.3 ) + 30 = 30.01CIn the code example it isn't any clear because I got:...
The CPU is powered using 1.8V both on VDD as well as VDDA (4.7uH coil as well as 1n/100n/1u capacitors in power path).When I measure the Vbat pin (100n cap supporting) in the range 2V-3.6V using the ADC I always measure about 0.1V less than the volta...
