    Pulsin display on 4 7-segment LED displays

    For information, on my page http://www.alpmn.byethost32.com/4digitled.htm, besides the TM1637, I just added an article about the MC14489. It seemed to be out of date, but I just bought some from AliExpress. Enjoy ...

    Picaxe 08m2+ et le Module RF HC-12

    Hi PM et la Communauté Picaxe, Pour info: Ma page relative au HC-12 (http://www.alpmn.byethost32.com/433mhz.htm ) a été modifiée (voir ton Post #14). J'ai également ajouté un point relatif aux incompatibilités et fausses copies des HC-12. Merci pour ta collaboration.

    Picaxe 08m2+ et le Module RF HC-12

    Ci dessous un lien vers un data sheet de 109 pages que je viens de trouver. https://semtech.my.salesforce.com/sfc/p/#E0000000JelG/a/2R000000HTIE/.wr7MYcDJegmsXUflvtVGp7PiqAzdCaqRKXqRr3J8Y4 Du peu que j’ai pu voir après un rapide survol... c’est « un peu » plus compliqué que le HC12! Nombreux...

    Picaxe 08m2+ et le Module RF HC-12

    Merci PM. je vais essayer un de ces lora. y a t-il moyen de configurer plusieurs canaux différents (comme sur le nrf24l01+)? je viens de voir qu’il comprendrait 84 canaux mais je ńai pas trouvé de datasheet complet expliquant les diverses configurations dont les canaux.

    Picaxe 08m2+ et le Module RF HC-12

    Existe t-il un data sheet complet expliquant le protocole de communication du module Lora? (Il me semble qu’il existe divers modules lora différents). en effet, je viens de voir un modele de 100mW (2km annoncé), un autre de 1W(!) annoncé 8km,...,... Un programme pour picaxe serait il déjà...

    Pulsin display on 4 7-segment LED displays

    Hi Aries, I am very impatient to receive my module to be able to test all this and finalize my web page on this driver. thanks very much.

    Picaxe 08m2+ et le Module RF HC-12

    Bonsoir PieM. Merci pour le compliment. L’etude du nRf24L01+ m’a en effet pris plusieurs mois. Concernant le HC12 je vais reconsidérer et reformuler cette phrase équivoque. Concernant les Fakes modules je n’ai pas d’expérience. Est-il possible des les identifier d’une manière ou l’autre? pour le...

    Pulsin display on 4 7-segment LED displays

    Hi AllyCat, Thank you for your intervention. In fact, I relied on a post found on the Picaxe Forum FR on which Beusquet, Senior member, advised to "replace the 4-byte number decomposition loop by the bintoascii command, much faster"! But as I am waiting to receive a TM1637 module, I haven't been...

    Pulsin display on 4 7-segment LED displays

    Hi Aries, I read your comment and wonder. I previously used a calculation routine similar to the one you present. Namely: successive divisions based on the remains of the division. This routine consumes a lot of lines of code compared to a simple Bintoascii. So I'm not really sure that you are...

    Pulsin display on 4 7-segment LED displays

    Here is my optimised code inspired from various sources from which I have kept the most compact routines and comments from the Picaxe FR and GB forum specialists. But I'm waiting for a TM1637 module to test it... If you see an anomaly or an improvement (or if you are able to test it on a...

    Picaxe 08m2+ et le Module RF HC-12

    Bien le bonjour à la Communauté. J'avais commencé une bafouille sur le HC-12 et fais quelques essais dont je devrais encore publier les conclusions. http://www.alpmn.byethost32.com/433mhz.htm Sinon, j'ai publié une étude complète sur le fameux nRf24L01Plus qui offre une multitude de...

    Pulsin display on 4 7-segment LED displays

    Hello, I am therefore analyzing the TM1637 driver. I understand the control protocol. In fact, in series, we send the status of each segment of each display. The decimal point is obtained by adding 128 to the code of the search character. Question: How to light up the two vertical dots used in...

    Pulsin display on 4 7-segment LED displays

    Thank you for your interventions. An interesting post had been published for the TM1637 with an optimized program: https://picaxeforum.co.uk/threads/easy-4-digit-led-display.30037/#post-323425https://picaxeforum.co.uk/threads/easy-4-digit-led-display.30037/#post-323425

    PWMOUT Wizard Bug ??

    Just for fun. I corrected and improved my Excel file to calculate Period and Duty Cycle values. (PwmOut Wizard) It checks and validates the possible data for each type of Picaxe: admissible frequency, prescaler and clock ranges. The specific data specific to each Picaxe can be selected from a...

    Pulsin display on 4 7-segment LED displays

    Hi, I remember that I had used a Motorola MC14489P driven with successive SHIFTOUT commands with a Basic Stamp. Circuit capable of driving up to 5 digits and requiring only three inputs: Data_in, Clock, \Enable. I will also research in this direction and see if an adaptation is possible with a...

    Pulsin display on 4 7-segment LED displays

    hi everyone, I would like to display the result of a pulsin measurement with an 08M2 picaxe (0.8 to 2.2 msec) on a 4-digit 7-segment red led display. The display would therefore be 800 to 2200 (the first zero from 800 to 999 not lighting up). Which driver for 4 7-segment led displays would you...

    PWMOUT Wizard Bug ??

    Hi AllyCat, Indeed, there are several parameters to take into account to be complete. Seeking to understand, I finally think I wrote the complete formula in my excel file attached above. My results are confirmed if I check in parallel with the PwmOut Wizard. (Sometimes just down to one unit)...
