Re: OV7670, Generic STM32F103RC and ILI9341 display

Have You guys seen this? https://www.youtube.com/watch?v=TqSY6FETuos He made a huge thing 10fps on Arduino. I will be trying to run it on maple mini. He has all code on github also for stm! worth to try! Thats pretty impressive, but be aware ... according to the comments on the video "The tric...

Re: $10 O-Scope revisited

BW is there a schematic? Although it looks pretty self explanatory, it might avoid me making any smoke releasing assumptions.

Re: $10 O-Scope revisited

@Andy Hull, I would like to send one of my boards to you so you can play with it and see what you can come up with using a TFT shield rather than a SPI TFT. If you would be interested, please PM me. I'll fit the components, you just need a screen. Board received, thanks. :D Blinkenlights are a-blin...

Unix on an SMT32F103... maybe

I spotted this and it got me thinking...

... since we can emulate a 6502 and even with some effort a Z80, we might be able to fire up a $ command prompt.

Re: 'ON' Button circuit

Diodes... More specifically, you probably need a Schottky diode in line with one or both power inputs to stop you from feeding one supply with the voltage of the other. Simple rectifier diodes may work, but may have too much voltage drop. Things become more complicated if your batteries are recharge...

Re: 'ON' Button circuit

Although the STM32F103 doesn't have a built in touch controller, you might be able to use the method described here to allow you to add touch buttons. VRQ3XJO1VFo https://www.youtube.com/watch?v=VRQ3XJO1VFo +Ekawahyu Susilo Yup, touch control is implemented in software using pure GPIO functionality....

Re: I killed my Maple Mini

Throw some cold ice on it :mrgreen: I may try with some nitrogen :D I did not even understand how I managed to do this. It was connected to a board with several buttons and I was soldering some diodes to this board. Later when I switched on the power, the maple mini was not working anymore :) I cha...

Re: Fuses and Circuit Breakers

A combination of quick blow fuses and resetable fuses or breakers might work for what you are doing, assuming the current to be relatively modest. A short circuit would blow the quick blow hopefully before irreparable damage is done to the controller and the resettable fuse or breaker would protect ...
