Re: VCC-GND STM32F407VET6 dev board

So, I've purchased one of the STM32f407VET6 dev boards from a company called vcc-gnd with a goal to porting MicroPython to it. I have a pyboard 1.0 with a STM32f405, which is in the same family, so it shouldn't be too hard to port across. http://i.imgur.com/ruEhY81.jpg Does anyone else have one of ...

Re: STM32F407 FSMC memory

I have used the FSMC to drive an external TFT in 16 bit parallel as the screen RAM is just seen as external RAM by the STM32F407VET. Here is the code https://github.com/OutOfTheBots/ili9341_16bit_touch that was part of the development for this video https://www.youtube.com/watch?v=H51OzQl3BC8 I don'...

Re: ST7789 IPS 240x240 SPI display

I do have 1 of these little screens as they are quite cheap yet very high performance. It is just sitting on my desk as I have been super busy with other projects atm. I was going to use it like I have all my other screen by using Lobo port for ESP32 but with just a custom init(). Lobo port has a ve...

Re: TI ADS1219 ADC driver

A noob question here. If it is a 24bit ADC and your Vref is 3.3v then the sensitivity it has to read is 3.3v/(2**24) = 0.00000019669532775878905 volts What sort of hardware would be needed to decouple and isolate the ADC so that such fine voltages are not just inducted from the air?? I have used the...

Re: New MaixPy update, support KPU, openMV~

Great development.

I am amazed at what this platform is bringing and with it being supported by Micropython will make it so easy to use

Re: ESP32 w/oled - mem issue?

I think you misunderstand Roberthh answer. Basically when memory is allocated then there is less memory left on the heap. When that allocated memory is finished with it isn't returned to the heap until garbage collection is called. The automatic garbage collect will be called anytime the available h...
