MicroLisp Interpreter, I2C, SPI, WiFi and Graphics ... All in a single C source file amazing 🤔
Maybe we wrap up the #MicroLisp code in a graphical program like Scratch / Blockly? 🤔
Drag-n-drop #BL602 #uLisp Blinky with these blocks ... Code Generator coming soon ... Try it for yourself here: https://appkaki.github.io/blockly-ulisp/demos/code/
#Blockly works on Mobile too
Cool new way to run #BL602 firmware without putty and CoolTerm ... Just use Web Serial Terminal!
Sending the "reboot" command to #BL602 from a Web Browser ... Via Web Serial API
Proper way to send #BL602 the "reboot" command ... From Web Browser with Web Serial API
Yep we can send commands from our Web Browser to #BL602 ... Just use the Web Serial API!
How we send a command from Web Browser to #BL602 ... With the Web Serial API
@lupyuen I might have some insight into the SX1276? issue. It just occurred to me what to do.
Try using sudo and lsusb -v to measure the power being allocated to the BL602 board. I had readings of 98mA. An ammeter would work too. I don't think it's getting the power to emit more radiation.
@AmpBenzScientist Interesting... so we think BL602 might not have sufficient power for the LoRa Module?
Here's what I observed...
(1) BL602 + SX1276 seems to be emitting the right power (see the red chirp)...
(2) But BL602 + SX1262 seems to be emitting much less power (the faint chirp)...
If it's a power problem, why is SX1262 affected but not SX1276 🤔
@lupyuen SX1276 is the one I can't use but it's close to 1GHZ. The other uses a frequency about half of that.
@lupyuen As an American I will have scary people hunt me down and put me in the back of a van if I don't abide by FCC regulations. The SX1278 is the only one I can use. If I'm not mistaken it's 915mhz. I also live within rough sensor range of one of the largest Air Force Bases on the East Coast in the US.
@lupyuen No satellite dishes? They could mandate a mesh size for the parabolic reflector that would mitigate any potential problems for improper use.
@AmpBenzScientist Hmmm I'm a bit too distracted right now ... Gotta write up about Lisp on BL602 ... Then test the Pine64 LoRa Gateway.
I guess SX1262 works for now, even though it seems suboptimal
@lupyuen I'm going to shave with my safety razor. Electric shavers are not acceptable for a proper shave. I will be away for the typical 15 minutes it takes to shave with a safety razor.
@lupyuen I love China and especially under Xing pin. He's done much good for the country. I think his history shows the future of China.
@lupyuen Sorry. I know almost nothing about your country. In the US we are essentially taught about our history, Russia/USSR and China.
@PawelK @lupyuen These are very different transceivers. The SX1262 might take more energy but the bandwidth is closer to dial up speeds. That's almost double the SX1276. The SX1276 looks like it's losing on all levels. The transmission is a bit more sophisticated and I will need to review the SDR readings to try to better understand what is going on here.
@PawelK @lupyuen It's just a product from Pine. I am not aware of a product they have made that has worked without a massive community effort. Pine makes hardware. The community makes the hardware work. When I got my Braveheart I thought it was broken after a couple of uses. I took it completely apart and photographed it.
It was not broken by me. The battery discharges when powered off and dies after a couple days. I found out why it was getting so hot during use and recommended thermal pads to the developers.
Lee is likely the reason why Pine didn't die. As far as I've seen, he's been involved with every product that they have made. Imagine buying a product that doesn't work at all, working to make it work and never getting paid for it. That's what we do. It's for the community, it's for the knowledge we gain and most importantly for the future.
@PawelK @lupyuen My Pinephone came with no Operating System which was a good thing. I tried to get involved in porting Debian to the device but Ubuntu circle jerk crew hoarded all the code so that they could get all the glory. They got left behind and eventually had to admit that they were not releasing the code. Pine just takes existing components and combines them into a product.
My best guess is lineageos purism or grapheneos. I hear your critique but they risk something too and we can get best of two worlds. They release beta community fixes it either they release fixed one and become superstar or we do. In their model sane corpos can cooperate with fossworld. Lets try out that model.
@PawelK @lupyuen Someone built a working Linux cellphone with a BeagleBone Black before Purism made its device. The Pinephone is not the first Linux Smartphone, that would be the Openmoko. The Pinebook wasn't the first arm powered Linux laptop, the Chromebook was. Pine needs to have a leadership change. I don't see a real future for the company as they were not much better than Orange Pi. The best company was NTC. They broke barriers and should still be referenced to this day.
