success.. success! The 16x2 display can be controlled immediately with Phil's sample program. I just have to slim it down a bit but other than that it's exactly what I was looking for! Thanks a lot for this! Regards wolfgang

Thank you for the example programs! I'm experimenting with it. Regards wolfgang

Hi Phil basically, this display is exactly what I could use for a student project because only two lines are needed and because the entire display with driver board only costs 3.2 euros! Since the students have to pay for the display themselves, I have problems with 18 euros for the AXE133...

With an Arduino and the appropriate library, I have now been able to control the display. It's a pity that there doesn't seem to be anything like that for the Picaxe. I actually thought that the PCF8574 would already take over the entire control of the display, but that is probably not the case...

I found the address with an address scanner for an Arduino with 0x27 but there is also the bit 0 =1 I couldn't find a clear example.

Hi, everyone, I'm currently trying to output texts on an I2C display with HD44780 controller, which unfortunately I can't do. On the supplier's side, the address is Hex 3F, but if I set this address like this: "hi2csetup i2cmaster, $3F, i2cslow, i2cbyte" , then there is an error message that...

This is exactly the problem that I don't want to use an X1 or X2 but just an M or M2! I'm not quite sure why I can't do a transfer with I2C, even though the 74HC164 is not an I2C chip! The data is shifted out and arrives in the 74HC164 as usual bit by bit! I know that the I2C is not designed for...

Is it possible with Hi2cout ? 400Khz are already quite fast! And all M2 know the hi2cout.

Thanks a lot. This is how the program now runs and shows the numbers 1 to 8 from top left to bottom right. If you put one or two sheets of paper over the display, the dark segments are almost completely hidden and the numbers are easy to read. Nothing flickers anymore. You could speed up the...

It looks like "DATpin = bit7" does not set the output

I use the 18M2 The data is only clocked with the positiv edges of the CP. If the bits are only applied to the data input but then no clock is received, they cannot be transferred into the display. This is not possible!

I think the key is the speed with which you can get the data into the display! This routine is too slow! How could you speed up the output? for i = 0 to 7 temp = val & %00000001 ; mask bit 0 using bitwise AND if temp = 1 then HIGH dat else LOW dat endif...

Today I measured the board a little bit. The first byte is used to compose the segments and the second byte is used to select which of the eight digits should display it. With the clock input the data is pushed bit by bit into the display. Since all bits are pushed through the selection byte...

Thanks for your information! I only found this minidocu, but it doesn't really make sense. This module is ideally suited to adding a 2 line 4 digit red 7 segment display to your project. This module lets you display your information in a bold and bright way, writing all manners of numbers and...

Can someone tell me how to control the display? https://www.pollin.de/p/digitalanzeige-modul-daypower-lc-display-dig-2r-810568 It only has 4 connections: GND, VCC, Data, Clk The two 4 x 7 digits displays are addressed via two shift registers 74HC164 but I can't find anywhere how to address a...

Hello, is it possible to send a message to a mobile phone with a Picaxe? In other words, is there a module to send SMS messages to a mobile phone? greetings Wolfgang

Hi, ffor a project I must measure the temperature and the air humidity. For it I have got myself the HYT 221. https://www.ist-usadivision.com/objects/media/data-sheets/product/humidity-module/HYT-221.pdf With an Arduino and this programme I can select the values / register Code: #include...
