Re: [SOLVED] The fastest ADC (analogRead) - how ?

Code https://github.com/arpruss/stm32scope-e ... /scope.ino works on F4 BLACK !

A huge thank you stevestrong for assistance in adapting this example to F407VET6 !

Re: [libmaple] Black F407VET6

Thank You for Your tremendous work.
You have so much done !!!
You're probably only ADC !
We will wait for a quick solution.

Thank You again.

Re: [libmaple] Black F407VET6

Hello Steven. I was able to do as you told me. The error no longer exists. But ADC is not working correctly, the values are constantly jumping (subject to change). I tried to connect the ADC pin to GND and VCC, the values still vary over a wide range. Tried using analogRead () all the same - value j...

Re: [libmaple] Black F407VET6

Hello Steven

Rewrote all the code in &ADCx, but the error persists



dataPoints[j+1] = &ADC2->regs->DR & ADC_DR_DATA;

base operand of '->' has non-pointer type 'const adc_dev'


In this line, correct the code ?

Re: [libmaple] Black F407VET6

Hello Steven !

I hear You.
You did a great job by adding support STM32F4.
I really hope that You will be able to add support for ADC on this Board.

Steven Thank you. This error is gone , but there were other dc_read:412: error: base operand of '->' has non-pointer type 'const adc_dev' on line dataPoints[j+1] = ADC2->regs->DR & ADC_DR_DATA; void fetch() { // const adc_dev *dev = PIN_MAP[analogInPin].adc_device; int channel = PIN_MAP[analogInPin]...

Re: [libmaple] Black F407VET6

Hello Steven. Doing a project in which I need a fast ADC. Took example code https://github.com/arpruss/stm32scope-experiment/blob/master/scope.ino . It is compiled on the Board STM32F1* great. But the Board STM32F407VET6 error error: cannot convert 'const adc_dev' to 'const adc_dev*' for argument '1...
