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...
I have generated the code (LED PB7 GPIO_OUT) by using STM32Cube Mx for MDK ARM5. While loading the code , I am getting following error.Contents mismatch at: 08001000H (Flash=00H Required=31H) !I have resolve this issue by erasing the flash using ST-L...
How can I calculate the supply current of the MCU (STM32L471) in unprogrammed state? We use it in an ultra-low power application and need to know the battery drain during production and storage.
