Re: Micropython

Yes, indeed you can. http://micropython.org/download is the place to get the binaries. https://www.cnx-software.com/2017/10/16/esp32-micropython-tutorials/ is a decent tutorial on getting going. The ESP32 has a very powerful processor and a decent amount of memory and makes quite a good micropython ...

Re: Switching code banks

I don't think so. I have to look at the source code to see if it can be done. If it can be done it will be done using a parameter that is read during the auto run phase.

Re: How-To BASIC Programming Logic Question...

The small program below does what you want. The test AdcNew < OldAdc-2 prevents the moving LSB from generating a message. The MAP function translates the code from the ADC to a voltage reading. An ADC reading 0f 0 is 0V and a reading of 1023 is 3.3V. The WaitTime loop at the end makes the code run o...

Re: Output a byte

One of the downsides of a 32-bit processor is that some byte oriented operations are a bit awkward; you have found one. On an LPC2136 the IO ports are 32-bits wide and IO can be awkward. Since bit-banging pins are a common operation I implemented bit IO and lived with some bulky code to do four bit ...

Re: PB1 Legend Error

I noticed on the board I receved that the area is not blocked out and the 3v and gnd pin are unpopulated, Does this mean that the Vin and gnd whitch are populated are ok? This is an uncorrected board. The Vin, Gnd that is populated is the output of the 3.3V regulator. The unpopulated position is Vi...

Re: Who are you?

HI, I am a design engineer from Italy who trained in England in the '80s (close to retirement). I also appreciate the Queen's english. I am dealing with several microcontrollers at work and still like to do something at home, mainly with PICs for ease of use. I find your product interesting except ...

Re: Interrupts?

Hi Mark "If I wanted to convert a number, say and integer, to ascii for display on an lcd, which command should I use--bin$, bstr, byte$, or bytestr?" Functions that return a string end in a $. BIN$ and BYTE$ will convert integer to ASCII representation (strings). BIN$ will produce a strin...

PB1 Legend Error

During testing it was found that the latest batch of PCB's have an error on the legend for the two pin headers with the output of the voltage regulators. The legend for the 3.3V output is swapped with the Vin legend. The polarity indicators are all correct. Since we found the problem we stopped popu...

I2C pinout correction

In the manual and on the pinout diagram the SDA and SCL pins are reversed. Pin 4 is definitely SCL and Pin 5 is SDA. The PB1 connections are correct.

Re: Interrupts?

Yes, there is a way to update the firmware. If you see an updated manual and you would like the new firmware, send an email with the serial number on the bottom of the module and we will supply you the firmware and a recipe to install it on your module. All the recent fixes have been small bug fixes...

Shipping/Postage Costs from ezsbc.com

After fighting with the shipping cost calculator on the site we have a new shipping policy. Everything we sell is rugged enough to be shipped as long as it is in a bubble padded envelope or a a small box. We have UPS as an option for shipping but the preferred shipping method is through the US Posta...

Re: Interrupts?

The PULSIN and PULSOUT are blocking functions. Nothing else happens while they are executing except the background counter increments. The manual on the web site matches firmware 0.63 and earlier. The latest firmware 0.64 is in testing and has external interrupt support on rising or falling edges on...

Tera Term Setup

I had a 'Windows' failure over the weekend and ended up re-installing Windows on my development machine. Today I tested some boards for delivery and discovered a new 'feature' in Tera Term. Every time I plug a new EzSBC1 into the computer Windows assigns it a new COM port number so I got pretty good...

Re: BASIC Implicit Explicit and Value Typing

Except for dimensioned arrays (DIM) all variables are integer/floats except for names that end in $ which are strings. Integers are 32 bit in size but auto-convert to floats if they overflow, underflow or are assigned a floating point variable. You may safely think of all numeric variables as floati...

Re: Shipping/Postage Costs from ezsbc.com

I have issues with the shipping calculator on the web site. I will investigate and fix it. Thanks for bringing it to my attention. I've seen several abandoned carts recently and this must be the reason. I will have it fixed as soon as the webmaster is awake. He is in a different time zone. Daniel
