Discussion - EVE / Re: Modifying ESD project to work in low power environment with RTOS
« on: December 02, 2022, 01:33:05 PM »
Thanks for the answers. I've been working on other projects for a while, but I'm getting back to this again.

This clarifies matters a bit. I think I'll be able to get this working now.

@Domdom I'm getting RF packets from industrial machines as one data source. That will be pre-processed by the microcontroller and result in "sensor-like" readings in some cases. I also have physical "soft button" membrane switches around the edges of the screen. The reason we don't use touch is because it might be unreliable and prone to failure in a factory environment.

Discussion - EVE / Modifying ESD project to work in low power environment with RTOS
« on: November 16, 2022, 11:23:56 AM »
Hi everybody

I'm trying to use a BT816 chip with ESD in a project. The device will be battery powered, so enabling the processor to go to low power modes would be very useful. Unfortunately, it seems like the ESD output is not written with that in mind: http://www.brtcommunity.com/index.php?topic=394.

In this thread a user alluded to the possibility of modifying the generated output to work with RTOS event loop. Did anybody do that? Is there an example I can follow?

What I have tried

I have got both the EvChargePoint demo and the TIM2 interrupt clock running on a Nucleo-STM32L476RG. I do understand the porting process. I'm getting stuck at how to enable the screen task communicate with my button handler, monitoring thread (temperature, voltages, current, charger status) and communications handler.

What I need to do

I need to update the screen when buttons are pushed, when the temperature/voltage/current/charge changes state and when I receive messages. Animations are not out of the question. I do not need any touch screen functionality for now. The product will be used in a -20C freezer room, so it has a perspex plate over the screen and is in an IP67 enclosure. Touch isn't viable/practical.

What is my best option? I have looked at ESE as well, but the widgets from ESD just look easier to get to look good.

Discussion - EVE / Flash memory to use with ESD and BT816
« on: October 06, 2022, 02:31:39 PM »
Is it possible to use W25Q512JVFIQ flash for the QSPI flash attached to the BT816 QSPI master interface with an ESD project? I don't see the option for W25Q512 in the Flash settings. Do we need to use a different flash chip if we want 512Mbit flash with an ESD project?

I got the demo working with MPSSE and FTDI cable, and then successfully ported to STM32L476RG.

I did a complete reinstall of 4.15 and made sure to not accidentally change any settings prior to first building the project as-is. That solved my issue. I think I must have changed some setting accidentally. I do think it's much too easy to accidentally change something, but the example is working now in the emulator.

Hi

I'm not getting the EvChargePoint demo to work on either ESD 4.15.1 or 4.8 on the emulator. I'm getting errors during code generation. Do I need any extra tools installed?

I replaced 4.8 with 4.15, since the only reason I had 4.8 is the confusing structure of the FTDI/Bridgetek website migrations.

I can post my errors if necessary.
