Impressive price point. I'd like to understand, what can you realistically do with these?

- dgacmu 2y agoThe 48 bytes of sram are enough to encode several state machines. It has pwm and dedicated IR signalling output, but no ADC for input. It's generally designed to be a very simple controller-of-things. Push an up button, increase the pwm output up to some limit, etc. remote controls, fans, etc.,
- zootboy 2y agoIndeed. I've seen a retail toy use a similar microcontroller from Nyquest to accept infrared control commands and drive some H-bridge drivers to make a simple, cheap RC car.

- eternityforest 2y agoIt looks like this chip is powerful enough to run a more "cinematic" looking gust/wind/topple/rise flicker model: https://blackdice.github.io/Candle/ https://blackdice.github.io/Candle/
- dragontamer 2y agoThe 38kHz signal support clearly indicates that this is a TV Remote Control chip.
- cpldcpu 2y agoYeah, you can find them in all kinds of low-cost remote controls: https://cdn.hackaday.io/images/9838991700773145118.file-1700773145085-572960022 https://cdn.hackaday.io/images/9838991700773145118.file-1700...
- cpldcpu 2y agoUse a neural network to detect numbers? (Well, this runs on a slightly more capable MCU, though) https://cpldcpu.wordpress.com/2024/05/02/machine-learning-mnist-inference-on-the-3-cent-microcontroller/ https://cpldcpu.wordpress.com/2024/05/02/machine-learning-mn...
- azubinski 2y agoNothing.
- theamk 2y agoMost simple home appliances - microwave, air fryer, mixer/blender of some sort. Toys, like a house which blinks lights and plays tinny music when a button is pressed (as long as speech / complex sounds atr bot involved) Remote control toys (with external transceiver)
