OpenGD77

I've been trying this afternoon with different values in the for() loop. If I use the code you sent me, I need 3 iterations in the first for() delay, six in the second and three in the third. Changing the values in the for() loops seems to be really sensitive, as only with those values I get any com...

After hours and hours I found one of the problems... my code was right but I had MOSI and MISO mixed up :lol: I got confused because, for the flash's SPI, in gpio.h MOSI is labeled DO, and MISO is labeled DI; whereas for SPI0 and SPI1 is the other way round. So I was sending the data to the C6000's ...

Check the clock edge / polarity for the SPI to the C6000, it may not be the same as the Flash chip. I'll email you some code but its not for the MK22 so would need modification to run on your hardware I had already tried both clock edge configurations. :cry: I’m sure it’s gonna be some little mista...

I have seen some other radios where the SPI to the C6000 had to be bit-banged. Just copy the Flash SPI code Yes. I've noticed that the RT3S/MD-UV380 doesn't use MCU's native SPI like the GD77, etc. and instead they connected the C6000 to random GPIO pins in the MCU. Looks like this radio works in a...

Do you plan to connect a better display Not really, as I'd have to make a hole in the casing. The stock screen is kind of "hidden" behind the case, and only appears when it's on. I think it's kind of cool. A better display would add more functionality but as I use this radio as a kind of simple and...

A bit tricky to solder, but it might just work ;) Hope I'm not too crazy :lol: ***pinout deleted, will add it back when it's corrected*** I checked and I think there's enough space in that part of the radio to fit all the components (there's no keyboard or anything so the front bottom part is empty

Yes, a colleague got such an instance of UV390. Released in December 2022.

Hope that doesn't happen to me I contacted the seller and the serial number starts with 2203, so I hope it's old stock and it's compatible. We'll see when I get it

I think the UV380 has multiple GPIO's which need to be enabled when transmitting, or receiving, but we don't know why Good. The more I investigate this hardware, the more I'm sure it's in some kind of middle ground between the GD77 and the MD-UV3x0. It uses the same rotary and a similar amp section...

However, its strange that this problem does not occur on the VFO or Channel screen, as the C6000 is always put in sleep mode, regardless of the screen. It’s also weird that it only happens with the rotary and not the keys. Maybe the interrupt of the rotary control is too quick and it doesn’t leave ...

Tried it on RT3S (Dec 15 2022) and I could reproduce it with eco level 2-5 , not sure if I can trigger it on level 1. Good! I was starting to think it was a hardware fault in my radio. I can trigger it on level 1 but you have to leave the radio untouched for 20+ seconds in a menu. Then turn the rot...
