Something on F1C100s by piotr_go
Hello
I honestly admit that I do not know yet what exactly will be built. For now, I am trying to run what I can from the interfaces available in the system.
What is F1C100s? It is a Chinese SOC in the QFN88 housing with:
- ARM9 processor (not to be confused with Cortex A9)
- 32MB RAM (built-in DDR1)
- LCD controller
- camera input
- composite input / output (TV in / out)
- audio codec
- resistive touch controller for LCD
- USB / SD / MMU / DMA / Timers / ....
The layout cost is approximately $ 2.
I will be using the Lichee Pi Nano tile for my experiments.
Some time ago I bought a few items and they were waiting for their turn.
The soft on which I base my experiments can be downloaded HERE .
At the moment I was able to run VGA (640x480) through the converter board connected to the LCD connector.
I also have a matching LCD touchscreen that I will want to run.

Cool baby :D It is a pity that I do not have enough programming knowledge, but with such resources (and dimensions) I would think of some SDR receiver. The built-in audio codec in the case of "W" can be... [Read more]
Codec on the list of things to run, right after SD. Currently I deal with LCD and touch. Of course, it's about soft without using Linux, so that the whole thing starts in less than a second. [Read more]
While the DAC in the codec looks interesting (two 8-192kHz channels), the ADC is poor (one 8-48kHz channel). For the SDR you would need to provide an external two-channel ADC. What is this converter?... [Read more]
Something on the "GM7123" scalak, probably ADV7123 clone. I have 800x480 torn from navigation. It works. I'll post a video tomorrow. [Read more]
I also have a few of them, I wonder if the pinout is correct. [Read more]
LCD, touch, UART, SPI FLASH are already working, so that HMI display can be done. [Read more]
Watch https://www.youtube.com/watch?v=cwCxkLZRuN0 F1C100s probably has more computing power than STM32F407? [Read more]
There is no FPU so there could be a problem. However, there is a similar SOC - V3s with Cortex A7 core and FPU. The housing is only slightly larger (LQFP128). [Read more]
In fact, I didn't look at the DS in this respect. Probably without FPU it will not be able to handle DSP processing in SDR. You mean something like that? https://www.ebay.com/itm/Lichee-Pi-Zero-A... [Read more]
Yes. This one. ========= update 04/28/2020 ========= I was supposed to run the SD first, but I started working on the DAC first. Sound, DMA, interrupts are working. Now there is SD. =========... [Read more]
========= update 05/02/2020 ========= I have pinpointed the cause of the low FPS. Data cache was disabled :D Now DOOM flashes in full screen. By the way, I launched hardware color indexing. [Read more]
https://obrazki.elektroda.pl/8833326300_1589812869.png PCB ordered, I hope it does not sleep ........ :) F1C200s (64MB) + LCD + AV + USB-C + uSD + SPI + I2C + I2S + UART ... Dimensions: 50x50mm [Read more]
I can see that the work is progressing. [Read more]
https://obrazki.elektroda.pl/4475895000_1592593526_thumb.jpg Tested, it works. Now it just stayed soft. Some simple OS would be handy to be able to load programs from the card. I'll take care... [Read more]
How is it, some? Just linux :) https://www.thirtythreeforty.net/posts/2020/02/trying-the-allwinner-f1c200s/ [Read more]
Nah, and will I wait 3-5 seconds for it to take off? :) I'll try to write something myself. I'll see what comes out of this. I already have drivers for everything. Today I launched a new display... [Read more]
Maybe some interface for PS @ or USB to the keyboard because I am proud to play it :D I ask kindly :) [Read more]
Pretty neat tile came out. [Read more]
I forgot about the USB completely, I don't have this driver. It will probably come off a bit because the USB chapter has only 3 pages in PDF. ... unless I connect via UART using this . [Read more]
