Re: Raspberry Pi 4 and Ultibo

Time for a Pi4 survey? Where should Garry and team focus? we all knew the Pi4 was coming but it was in no way expected until 2020 so we thought we had time to complete some other work first. Yep how dare they bring it out early, I was hoping for at least another year of learning on the other Pi's. I...

Re: Raspberry Pi 4 and Ultibo

Invest time in the current Pi support completion (e.g. wireless networking) or the support of the new and radical different Pi 4? Same wifi/ble chip in 3B+ and 4B? And probably in the Pi5 too? So effort there will not be wasted. Some is new, some is old. What is the minimum needed to get the Pi4B t...

Re: Raspberry Pi 4 and Ultibo

We've ordered ourselves one which will take a week Core Electronics had some 1GB in stock, should get one here Thursday? The 4GB will replace my home Linux box for Pi development, but that is next month? Ultiboinstaller.sh should just work? Some of the stuff should be easy once register addresses a...

Re: There is a RPi4 on the wild

The question is... how much work and time will it get to port Ultibo to this new board... And can we get Ultibo into that 4Mb EEPROM second stage bootloader? :lol: VC6 :o not even a VC5 and it does Vulkan, that will be really interesting. In case anyone has forgotten :D https://github.com/BeRo1985/...

Re: Broadcom & voltage

eMMC has it's own voltage. https://www.raspberrypi.org/documentation/hardware/computemodule/datasheets/rpi_DATA_CM_2p0.pdf This would be hardwired on normal Pi's? but on Computes you could change the GPIO voltages. Could be handy for 1.8V i2c etc. I have never used Computes, thanks for the question....

Re: Broadcom & voltage

A very good question I did not know the answer too. Compute module CM3+ datasheet page 15 Bank0 and 1 GPIOs are available for general use. GPIO0 to GPIO27 are bank0 and GPIO28-45 makeup bank1. GPIO0-27VDD is the power supply for bank0 and GPIO28-45VDD is the power supply forbank1. SDXVDD is the supp...

Re: Pascal on Arduino?

Your "FUNCTION" should more properly be "PROCEDURE". Thanks for the correction, I was still in C mode thinking. Keep forgetting Pascal has functions and procedures :D Nested PROCEDURES? Are they needed if predefined prototyped? Anyway, real free pascal on Arduino's could probabl...

Re: Booting from secondary SD card in Pi Zero?

I have only programmed the OTP boot mode option on Pi3B's. The Pi3B+ come with it preprogrammed, both use the BCM2837. Does the Zero(BCM2835) have OTP boot options? Compute module has eMMC and USB modes https://www.raspberrypi.org/documentation/hardware/raspberrypi/otpbits.md https://www.raspberrypi...

Pascal on Arduino?

One of the guys on the Pi forum showed me a C #define trick. Since I used Arduino for the Microbit stuff I thought this might be fun. I have used #define lots of times in C but never to make C look like another language. Blink example #define BEGIN { #define END } #define FUNCTION void FUNCTION setu...

Re: eBook reader

This OpenVG stuff works on the Pi 7" screen. https://ultibo.org/forum/viewtopic.php?f=14&t=1332&p=9153#p9153 I probably need to make a book reader app to see if this 7" is good enough for text reading. I don't think it will look too good on a lower res screen. The 4" Hyperpixe...
