@byte_thrasher Use TI-MSPM0C1104(ti.com/product/MSPM0C…) + Voltage Divider Sense Voltage Divider using ADC from MSPM0, then use I2C based or 1-wire based protocol to read from it... It's super small and few projects already use it as an emulated EEPROM

I want one of my PCBs to be able to report its revision number to the MCU. I can dedicate exactly one pin to this task. What is the cheapest and easiest way to do this? Let's assume 20 revs (lol). First idea that comes to mind is a simple voltage divider. Might be good enough

@beaversteever Try Verible, it works like a charm

i need an automatic code formatter for verilog plz give me ideas i don't want to empty a water reserve just to find out

🎉 Zephyr Project Meetup Bangalore recap: Two tracks, demos, dynamic panel, free BeaglePlay boards, & networking time! Huge thanks to @TXInstruments for hosting (venue, food & drinks), our speakers for sharing insights, and all awesome attendees. hubs.la/Q03qxG2T0

@b0jle I think you will get good BLE ICs with less than a dollar from known vendors like TI, Nordic Semi or Silabs.

i've been thinking about the uc ble chips that cheap chinese smartwatches that cost $2 dollars have. With good docs and hackable SDKs, those chips have so much potential

@cemaxecuter ti.com/product/CC1352… I'm not sure if this is supported in ExpressLRS but it can do both 915 MHz and 2.4 GHz

Which frequency band is more commonly used for ExpressLRS—2.4 GHz or 915 MHz? Also, if I want to pick up a transmitter/receiver to put on a drone for testing, any recommendations?

@rohan_devarc I'm already using their Tang Nano boards with yosys toolchain so I was curious to see their Tang Mega series but Thanks for the heads up. I have Vaaman and BeagleV-Fire on my list, will try those

At this point, I cannot recommend Tang Mega boards. While they are marketed as Gowin FPGA evaluation boards, they come with nuances and bugs that require professional experience to resolve. After months of effort, I was only able to get them working by getting a license and fixing over 120 issues. As it stands, It's not worth the work you've to put for getting the eval board to work.

Finally got LiteX as well as UART working on Tang Primer 25K with Linux. Sipeed example repo is not helpful. Some examples don't work on the board. - Had to fix driver for FT2232 so usb/jtag multiplexing can work properly. - Firmware has many bugs wrt UART. It's producing literal garbage. - So I grabbed my Logic analyzer to take a deeper look and solved that firmware bug. - Finally, to build LiteX, I had to patch the riscv toolchain then build it. @GOWIN_SEMI Linux compatibility is something that needs immediate attention. Not everyone who starts out with fpgas will be an expert at fixing broken stuff.

@rohan_devarc Where did you buy 138k board ? I only found tang nano series online

At this point, I managed to bringup every #GOWIN based fpga board on Linux. x.com/rohan_devarc/s…

@Vicharak_In Looks interesting !! Is there any direct way/link to purchase it apart from crowdsupply ?

🚀 🚀 Through tens of different revisions and prototypes, through iterations and failures, and under constant pressure to get them shipped, we are finally shipping Vaaman after almost two years of effort. We are shipping!

@octacons Thanks for the interesting CTF, it was a great learning experience, it would be great if you can share maybe solutions or writeups for the questions Looking forward to future CTFs ✌️

this weekend it will be held CTF (Capture The Flag) Signal. I've try to make the flowing story with beyond challenge CTF. prepare your tools.. 🤖🤖🤖🤞just for fun..

We've now wrapped up the third Summer of Math Exposition! youtu.be/6a1fLEToyvU

@zipcpu Is it because of i_ckstb? there is no check in that "if block" if the transaction is going on or it's just free running clock.

We haven't done a bug of the day in a while, so here is this week's embarrassment. After writing this, I convinced myself it was so simple that I could just move straight to hardware with it.

@sahajsarup Yeah, that seems an overkill for such applications, but I think most of the silicon labs radios have Cortex-M33 core while TI uses 8051 and Cortex M4 for their CC1352x series

@DevanshTanna That seems a bit op but the branding lines up, cortex-M33 just to control a relay while the used a cheaper and simpler 8051 based chip for the temperature and humidity sensor.

Got the SONOFF zigbee switch, anyone recognise this chip?

@xyz04274951 Try PlatformIO(@PlatformIO_Org) :)

This CMake thing is super confusing at the moment...😥

Heyo work towards a #SDR related #FPGA project in PipelineC continues as well. Trying for something like FM radio demodulation as a complete demo. High level notes are linked. Can you help? Need folks with background in the DSP needed for such a task 🤓 docs.google.com/document/d/1hj…

Hey folks are you interested in making a #RISCV core in #FPGA using PipelineC? We are putting together some initial plans now. Should make for some neat experiments between C source code for software vs describing the CPU hardware. 🤓 DM for edit access. docs.google.com/document/d/1L7…
