    ADF4351 PLL success load with a PICAXE20x2

    Hi Alan, I will experiment some more this evening. I found a doc form an other site using Arduino, the author also showed R5 to R1 and LE transition high to low then low to high in between each R dump. Regards Gerald

    ADF4351 PLL success load with a PICAXE20x2

    Hi, I am trying to make a 20x2 load a single frequency for a local oscillator. It appears to load, see logic capture below and the default freq shifts from 4.5GHz to 3.693GHz, but that falls short of the mark. Question without notice, has anyone tried a 20x2 on a ADF534x? 'VK3GJM, 2021...

    AGM battery State of charge, SOC

    Hi All, I am trying to build a dual volt meter 20x4 OLED using (20M2) that will monitor the main vehicle cranking battery and a lighter aux battery. Both batteries have a slightly different voltage value referenced to a SOC on %, thus I want to accurately map for an accurate result. How can...

    Driving 40x2 display with standard AXE133

    Hi All, I managed to obtain some very cheap Winstar WH4002-YYH 40x2 character displays. I used a standard AXE133 to drive a full character set across both lines 1 to 40 ( 80 total ) characters. The attached photo is a quick test. Regards Gerald VK3GJM

    AXE033 Display Problem

    Hi Technical. Yes I don't believe it either. It is what it is. I cannot tell you the brand, the marking is a QA Pass sticker with several numbers such as:- FECC7602E GRNNYBW-66LE 1564. Anyway it's working for now. I will purchase another display and try that to ensure AXE033 PIC image is not...

    AXE033 Display Problem

    Hi Guys, I know this is a old thread, but the AXE033 serial display is frustrating. Let me explain. To set the scene, I am using it with 20x2 on C.7 default internal clock. I write the first line "hello", this is OK. Move cursor to the start of at line 2 position 1, write "world", this...

    EPROM like look up data

    Hi All, Please excuse my simply request for information. I am very new to PICAXE and programming, but I consider myself a fast learner. I am trying to operate 2 sets of 4 relays that control 2 RF attenuators that will give me from zero to 121 dB off attenuation in 1dB steps. I have worked out...

    HSPIOUT controlling a ADF4106 PLL

    Hi All, I am new to this forum and new to PICAXE and programming Micro-controllers. I have a need to program a Phase Lock Loop ADF4106 register using SPI. The requirements is a fixed serial string to be sent to the PLL on power up and there will be no change to any register value. The...
