Hi, I have a random amplitude signal with 10 us period, coming from DAC channel 1 of the STM32 connected to some block with amplifier and switches. The block is finally connected to an input channel of the ADC within the STM32. The block ...
Hi,I'm using STM32H750B with a NOR flash (Winbond's W25128 chip). When the chip is configured as QPI mode. If polling SR1 using the auto polling function, it will throw error. But read SR directly and check the bits works.Any help? Thanks.
I am trying to acquire the amount of ticks a timer counts using a 50Hz signal (acquired from the mains using hardware). For this I use a EXTI8 interrupt where the 50Hz signal is sampled. I can see on the scope that this interrupts works perfectly (by...
On Fig 613 of RM0433, the SS connects to Vcc. According to 50.4.7, it is said the SS pin is free for GPIO when in software SS management mode.Does fig 613 mean SPIx_NSS pin can not be used GPIO when corrsponding SPI in software SS management mode?
Hello, I am using STM32F100CBT6B in my project and I am in need of having one more UART port and I came across following example folder STSW-STM32156. Please let me know if it is possible to instrument this file to the F1 Series. Thank you.
Hello, I would like to use an eMMC of 8GB with one of these three MCUs: STM32F411VET6, STM32F765VIT6 and STM32H7A3VIT6. Do these MCU support eMMC of 8GB and does ST provides working drivers for this(as this project must go fast)? Many thanks, jprobs...
Why does flasch memory lose saved data after being read and written after power off?Andrzej
Both pins 2 and 3 are incorrectly described:pin 2 is PC14-OSC32_INpin 3 is PC15-OSC32_OUTMaybe other 'L0xx DS are affected, too; I did not check.JW
I am using Nucleo-L4R5ZI-P board, I have flashed sleep mode selection sample code to check power consumption of all the modes, but in all the modes I am getting around 156uA.I have also tried by disabling debug mode but the result is same.How can I a...
Hi,I developed a firmware for STM32L496QGI6P and all went well. After some time we produced new devices and there we discovered a problem with the ADC. The only different with the new hardware was the "date code" of the STM32L496.With date code 749 I...
