Metro RP2350 take 5 🔄🌟🤞

Sometimes mistakes are made in prototyping; that's why they're prototypes. The error in rev D was funny: while making the QFN80 footprint, the pins got placed clockwise rather than widdershins. Not surprisingly, that board didn't come up at all, so here's a full rip-up and reroute, with the correct pinout this time! Fingers crossed. Hopefully, this is the final revision, and we can move on to other RP2350 boards we have cooking.

Points To Consider When Developing Embedded Software

Debugging is the process of fixing errors from a specific piece of software. It also looks for any software issues and fixes them. The majority of the time, this is done to prevent errors or unexpected behavior.

Fruit Jam RP2350B credit-card mini computer with all the fixin's 🍓🍇💾

We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html).

Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer.

When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? :) We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.

Buildroot App Integration on Allwinner A40i: Step-by-Step

1️⃣ Create package/helloworld directory

2️⃣ Write Config.in + helloworld.mk (case-sensitive!)

3️⃣ Enable in sun8iw11p1_hf_defconfig

4️⃣ make menuconfig → compile → pack

💡 Key Insights:

.mk scripts glue Buildroot’s build system to your app’s Makefile

Error Alert: Directly overwriting .config breaks builds! Use savedefconfig instead

Final binary lands in /bin post-compilation 📦

Trying the PIC16F15376 Curiosity Nano using the Mplab Code Configurator. Nano boards are very cheap and includes an onboard #programmer, so there is no need for an external programmer. You can program it directly from MPLABX ide once connected or by uploading a given HEX on the external drive that board creates when you connect it to computer. You can use also the USB port as CDC. Code Configurator on MPLAB X allows to setup all peripherals giving also some function examples but a little understanding of options is always needed. . . . . . . . . . . #electronics #embeddedsystems #coder #microchip #programming #coding #developer #developing #embeddeddeveloper #engineering #microcontroller #noarduino #mplab #pickit #mcu #coding #maker #making https://www.instagram.com/p/B6lxd9vICBb/?igshid=xiw7e4mcyae1
